In the United States, energy for household heating is generally sold using English units, e.g., therm, gal, and cord. A house in Wisconsin uses 1200 therms of thermal energy during the heating season. Calculate the cost of fuel if the furnace uses (a) natural gas with an efficiency of 70%; (b) No. 2 fuel oil, efficiency 65%; (c) kerosene, efficiency 99.9% (unvented); and (d) wood with l5% moisture with an efficiency of 50%. Use the data in Tables 2.2, 2.7, and 2.13. The efficiencies are based on the HHV. Assume the cost of natural gas is $8/MBtu, the cost of No. 2 fuel oil is $3/gal, the cost of kerosene is $3.50/gal, and the cost of wood is $100/cord. Assume the bulk density of cord wood is 30 lbm/ft3 .

A chemicals company wants to optimize the power consumption of their air compressors. Their Design Engineers proposed to replace their Single-stage Adiabatic Compressors with the following: a. Isothermal Compressorb. Two-stage Compressor with intercoolingc. Four-stage Compressor with intercooling In order to justify the replacement, the percentage of the energy per mass (J/g) saved by each proposed compressor system should be calculated. Savings should be at least 40%. Determine which of the three proposed compressors will meet the criterion. The flow rate of air required is 600 ft3/min at 70 °F and 14.7 psi, which should be compressed to a final pressure of 2,000 psig. The relative molecular mass of the gas is 28, isentropic constant is 1.40, and density of air is 1.204 kg/m3.

An air conditioning unit works by taking heat out of a room. As the refrigerant gas expands in the cooling coils, it absorbs heat from the circulating air in the room. This heat is then released as the refrigerant is compressed by the part of the unit that is directed out of the room. The unit serves like a heat pump for the room. Since a refrigerator works in a similar manner, can t also be used to maintain a cool temperature inside a room? Justify your answer.
